The 2026 WNBA season has arrived, and the addition of two new expansion teams is making the competition stiffer than ever. The chances of the Portland Fire or Toronto Tempo going all the way in an inaugural season are slim, but a handful of others have a legitimate shot to win the 2026 WNBA championship.

WNBA 2026 Champion Polymarket Odds
Most Traded WNBA 2026 Champion Outcomes
The "WNBA: 2026 Champion" market first opened on Polymarket on April 6th, but trading volume is still quite low at the moment. This can be expected, as it's hard to predict who will win it all before any games have been played.
Now that the season is officially underway, contracts are being bought at a good rate, and that should continue until the expected market close date of October 31st. For the moment, the New York Liberty (~31%) are by far the most popular "Yes" outcomes, with a handful of teams in the Liberty's rearview, including the Indiana Fever (~18%) and Las Vegas Aces (~17%).
Read on for our full breakdown of which teams are most likely to win the 2026 WNBA Championship.
WNBA 2026 Champion Prediction Market Analysis
It comes as no surprise that the majority of Polymarket traders are buying the Liberty "Yes" outcome. The roster was already stacked with the likes of Breanna Stewart and Sabrina Ionescu, and the offseason addition of Satou Sabally could be enough to put this team over the top.
New York finally won its first ring in 2024, but recent years have been dominated by Las Vegas. The Aces have been WNBA champions in three of the past four seasons, including last year, which is a big reason why the team has favorable WNBA championship odds on Polymarket.
A'ja Wilson has been especially vital to Las Vegas' recent dynasty, capturing Finals MVP honors in both 2023 and 2025. The rest of this incredible core remains intact as well, thanks to a trio of guards giving the Aces what is arguably the best backcourt in the league: Chelsea Gray (aka the "Point Gawd"), Jackie Young, and Jewell Loyd.
While these powerhouses may both be intriguing, traders shouldn't sleep on Indiana. Recent years haven't been kind to the Fever, last reaching the WNBA Finals over a decade ago in 2015. Still, optimism has steadily grown since Caitlin Clark's rookie year in 2024, when the team broke a long playoff drought.
2025 was another year of substantial growth, as Indiana won the Commissioner's Cup (WNBA in-season tournament) and gave Las Vegas fits in the semifinal of the WNBA playoffs. Clark had an injury-riddled 2025 but is back at full strength, forming a formidable backcourt duo with Kelsey Mitchell, who was in MVP form last season.
With all this in mind, there's a lot of value to be had buying "Yes" contracts for any of the teams mentioned above. Buying the "Yes" outcome is ~35 cents for the Liberty, and ~19 cents for either the Aces or Fever. While there isn't as much value on the "No" side of things, ~74 cents per contract for New York is reasonable as well.
